The article from the Yank Magazine would seem to be written for the average person which suggests that is mainly an informative article intended to tell the readers how long the writer expected the war to be.

While this article gave an actual time for the japaneese to surrender, two years is a long time to wage a war, and so it would suffice to say that the speaker didn't expect the japaneese to surrender soon, and seemed to think that rather than try and peacefully come to an agreement, we were going to have to force the japaneese to surrender. This article contributes to our understanding of the atomic bomb by showing that nobody knew the real effects of the bomb until it was dropped.
